Currently, switching regulators come with inductors that are by nature bulky and difficult to fit in or integrate with ASICs due to space and layout considerations. This disclosure describes a voltage regulator based on switched capacitors (SC) that eliminates external inductors, enabling the integration of the voltage regulator with the package and/or the die. Integrated voltage regulators are valued in ASIC packaging designs as they better support power-integrity challenges brought on by advanced computing and memory-bandwidth demands. The techniques leverage the presence of parasitic inductance present in the package or/and MLCC, rather than employ external inductances.
